JQuery to css write nth-child()

Question

so I need to make a slider for school. I know that I can use something like

.sliders img:nth-child(Index) {}

I know it need to be like

 $(".sliders img").css.........

My question is how to write Child Index value into nth-child using Jquery?

Answer 1

您使用字符串连接：

$(".sliders img:nth-child(" + index + ")").css.......

Answer 2

您可以使用.eq()避免难看的字符串连接。

$(".sliders img").eq(index - 1).css();
